Military call sign for the letters W T, short for white trash. Can be used to communicate secretly even in the presence of white trash. Obviously more popular as slang within the military community. Credit to Chico from the Peleliu.

Whiskey tango, three o'clock.
Interpretation: Look at the white trash to your right side.

WHITE TRASH
Referring to a person based on either their behavior, actions, look, or socioeconomic status. This is commonly use by Police, Fire and ER personnal without the person knowing they're being talked about

In the alphabet when talking in code on a radio alpha, bravo, charlie, delta, etc (A,B,C,D...)
W=whiskey, T=tango

when asked by your work partner "whats goin on?" after you tell them the story you end with "whiskey tango" they reply with "ahh ok" then everything comes into perspective. Think of the tv show COPS
